To all whom t may Concern.'

, coinprising` relatively revolublclinner `and Beit known that l, CII-mams P. Banner, a

citizen of the United States, and a resident oi Nortoll, in the county o'l'x Nortollrand State oi. Virgi1i`ia,liave invented a certain lnew and nsei'lul Radial Ball `"learing, ot

which the :l'illowing` is a speciiication.`

This invention relates to `hall-bearings opposed annular faces with racewaysebetween which halls are confined to reduce the iriction incident `to their relative rotation. Ball-bearings of this kind involve the dis advantage o travellingwith a great circle in simultaneous bearing upon two annular silriaces of different radii, with the `loalls in Contact with one another, or with means provided for spacing` them apart, with the result that `rubbing 'friction is unavoidahly present in the bearing'. Moreover, thelload" imposed lupon the hearing is not suiiiciently `distributed among the balls.

`The present inventionhas tor its object to. provide a radial hall-hearing; in which each hall travels upon a great circle oi its circumference in eontct'witli hut lone raceway,` and in which the halls `of al `row are held apart by `means which theoretically imposes no 'friction upon the halls.

Aiiurther object is to provide a hearing` in which either radial or axial thrust will `he uniformly distributed among the halls.

Figure 2 is rad` al section oit' the saine; Figure B is an external view with the outer race-wayv removed showing,` a group oit halls of the inner and outer rows in the relations which they assume when in use and as seen in the direction oil a radius of it. represents an inner ring and anouter eoncentric ring ol a radial ball-hearing. The inner ring has a race-way consisting` of a pair of tracks 1 receiving two rows of halls 2, 2, and 3 represents an Outer raceway which receivesa row of outer halls Ll, 4:. The halls .Q are preferably of smaller diameter than the balls 4, and they not only have a space hetween the rows in which they are arranged but similar spaces between the individual halls of each row, so that each hall l ot the outer row seats in `a nest composed of four the balls of the inner rows `is such that each outer hall contacts with each of the inner hulls in which it is nested, at a point which lies in the line connecting` the centres oi the contacting halls. In other words,`the halls hear against each other in great circles or the halls. l

i The` radial section of each track i of the inner raceway A is an arc whose radius is slightly larger than the radius of the ball 'that bears init, and whose center is inthe plane of thrust which is developed`l` in the halls of the inner rowas a result oi the wedging action of two outerhalls'thereon. ln other wordsthe centers oi the inner raceu'ay circles must be in planes` which are shown inprojection (Fig. 2) by the` lines Cl), CD. f

The track or raceway of the outer halls is a sector of a sphere whose center is at the intersection of the geometrical axis ot the whole bearing with the plane oi" the outer balls, with the result that the outer bearing member is permittedV to rotate upon any diameter thereof in assembling the balls with theV rings.

I do not herein claim the method ogt assemhling the balls'through means of rota"- i tion of theouter member, as this as well as :special meansthrough which to hold the halls in position hy magnetic attraction, iorms the subject matter of a separate application` I claim: i

l. ln a radial vballtearing, inner and outer raceways, two spaced rows oi2 halls seated 'uponA the inner raceway and confined thereinagainst outward displacement in the direction of the axis ot the hearing, and a" single row of halls seated in the outer raceway and rows of halls.

Q ,In aradial hall-bearing, inner and outer raceways, two spaced rows of balls seated upon the inner raceway and confined therein against outward displacement in the direction oi' the axis of the bearing, and a single row oit halls seated in the outer race way and hearing upon the two inner rows ot' halls; the transverse section of the tracks of each inner row of halls being an are whose radius is greater than that or the insupported upon the two inner llO ner balls and whose center is in the plane of the centers or the outer balls and the corresponding, inner ball. p

8. In a radial ball-bearing, inner and outer raceways, two spaced rows of balls seated upon the inner raceway and confine-d therein against outward displacement in the direction of the axis ot the bearing, and a single row ot balls seated in the outer raceway and supported lupon the two inner rows of balls, the `balls et said outer row dipping between the rows or the inner balls and also between the individual balls ot the respective rows.

In a radial ball-bearing, inne-r and outer raceuuays7 two spaced rows et balls seated upon the inner raceway and contincd therein against outward displacement in. the direction ot the axis ot the bearing, and a single row of balls seated in thel outer raceway and bearingupon the two inner y rows of balls7 the balls of said outer row dipping; between the rows of the inner balls and kalso between the individual balls ot the respective rows, and the lines et thrust between the balls of the outer row and those of the inner rows being coincident with the centers of the balls.

5. In a radial ball-bearing, inner and outer raceways, a pair of rows of balls seated upon the inner raceway and a single row of balls seated within the outer raceway; each ball in the outer row supported upon four balls of the two inner rows.

6. In a radial ball-bearing', inner and outer raceways7 a pair of rows ot balls seated upon the inner raceway and a single rowv of balls seated within the outer raccway;l the balls of the inner rows beinp; spaced both between the rows and between individual balls of the respective rows, and each ball of the outer row being seated upon four balls of the inner rows and the balls of the inner rows spacingapart those in said outer row.

7. In a radial ball-bearing, inner and outer raceways,r two rows ot balls seated upon the inner raceway and a single row of balls seated in the outer raeeway; the in .outer raceways. two spaced rows ol' dividual balls of the respeetire inner rows being` spaced apart and each ball of the outer row bearing upon tour balls olf' the inner rows and thereby distrilultinrr both radial loads and axial thrust upon the bearing, unit'orinlj,T among` all the balls ol the bearing.

8. In a radial ball-hearingg`r inner and outer raceways, two spaced rows ot balls seated upon the inner raceway and confined therein against outward. displacement in the direction of the axis ot the bearing; and a single row ot balls seated in the outer racewajy' and sulniorted upon the two inner rowsy of balls; the track ot the outer rufewa)v he ing' a portion oit a sphere whose center coincides with the `geometric axis ol' the bearing.

9. In a radial ball-heuring'7 inner and halls seated upon the inner raceway and eonlined therein against outward disphuicuient in the direction oitl the axis ol" the bear-nur.. and a single row ot balls seated in the, outer raccway and bearing` upon the two .inner rows ot balls; the track of the outer racewa)7 being; a portion of' a sphere whose center coincides` with the geometric axis ot the bearing and lies in the plane ol. the centers ot the outer row of balls.

l0. In a radial lndl-bearingr` inner and outer raceways, two spaced rows ot balls seated upon the inner raceway and confined therein against outward displacement in the direction of the axis et the bearing', and a single row of balls seated .in the outer raceway and supported upon the two inner rows of balls; the track ot the outer raceway being a portion of a sphere whose center lies .in the axis of the bearing wherebyv detection of the shaft is allowed without subjecting the balls to crainniingaction.
